APPARATUS FOR HEATlNG CARS.

SPECIFICATION forming part of Letters Patent No. 387,206, dated August '7, 1888.

Application filed March 10, 1887. Serial No. 230.3l7. (No model.)

.To all whom it may concern.-

Be it known that I, Tuouits H. BOTTOMLEY, of (lapse, in the county of St. Clair and State of Michigan, have invented new and useful Improvements in Apparatus for Heating Cars; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in apparatus for heating railway-cars.

The object of the invention is to provide means whereby the cars composing a train may be heated by steam from the locomotive.

To this end the invention consists in the peculiar construction and arrangement of the pipes and their connections, all as more fully hereinafter set forth.

Figure 1 represents a sectional view of two cars to which my heating system is applied. Fig. 2 is a sectional detail.

In the accompanying drawings, which form a part of this specification, A represents two railway-cars,in which is arranged a suitable system of radiators, B, connected to the steampipe C, each end of which is connected to a vertical pipe, D, which projects through the floor of the car and terminates in a horizontal pipe, E.

F is a coupling of larger diameter than the pipes E, which latter, when the cars are coupled together, project into the coupling F. In the lower side of this coupling F is arranged a suitable valve, I, to admit of the discharge of the Water of condensation. Upon each of the pipes D is secured, by means of a thumbscrew or other convenient means, a collar, J.

Beneath the coils B in each car is a pipe, K, which also connects with the stand or vertical pipes D, and each of these pipes C K is provided, preferably, with two-way cocks L.

In practice, the car next the locomotive is coupled by any convenient means to a pipe that communicates with the live steam of the locomotive. Supposing it to be desired that all the cars in the train provided with my device, as described, are to be heated by means of the radiators, the two-way cocks of the pipes K are closed, so as to admit of the free pipes of air and establishing a circulation of steam through the pipes.

\Vhen it is desired to uncouple the cars, one of the collars J is loosened and pushed back on the pipe E, which allows such coupling to be pushed back upon the pipe E.

Should it be desired to cut off the steam from the radiators in one or more cars, the two-way cocks which control the passage to such radiators should be closed and those of the pipes K opened, which will allow of a free circulation or passage of the steam through such pipe K, and thence on to the next car.

Should water of condensation accumulate in the coupling F under the ordinary pressure of steam employed, by the engineer giving an additional force or quantity of steam to the heating apparatus, such extraordinary pressure of steam would cause the valves I to open and allow the water of condensation to escape, the valves again seating themselves under the action of a suitable spring as soon as the extraordinary pressure of steam is removed.

YVhat I claim as my invention is In a system of heating cars, the combination of two stand-pipes supported at opposite ends of a car, projecting through the car-roof and open to the atmosphere, and provided at their lower ends with suitable couplings to connect between the cars, with a main pipe connecting the stand-pipes within the car, a radiating circuit independent of the said main pipe and connecting the two stand-pipes, and two-way valves at the connection of the stand-pipes with the main pipe and radiating-circuit, substantially as described.

THOS. H. BOTTOMLEY.
